WORKING STEPS

Open the catia software. Start/mechanical design/part design.

Select the XY plane. Select sketch icon.

The plane automatically rotates to normal. Draw the circle as per the given

dimensions.

Click to save the diagram with suitable

name.

Two circles are constrained to the

60mm gap.

Then select bi tangent line to form the

tangent around the circle.

Then click the trim tool to the unwanted

profile deduction.

Trim the unwanted.
